Care Instructions: Yoga mats release a very strong but harmless odor when first opened. Please unroll and air out your mat 2-3 days before use. Spot clean with our Yoga Mat Wash or damp cloth with cold water and mild detergent. Dry flat. The mat may fade and become brittle and unusable if exposed to the sun for extended periods of time. We recommend storing your mat in a mat bag when not in use.
